What Is Fiberglass Insulation Anyway?

At Lewis Insulation, we provide a variety of insulation services to help you keep your home safe and comfortable. And, one of the most popular types of insulation in the Twin Cities is fiberglass insulation. But, you may be asking yourself ‘what is fiberglass insulation anyway?’ We are here to answer that question for you!

Attic Insulation

What it is.

Fiberglass insulation is a type of insulation that’s made out of very thin strands of glass. It is a man-made material and has a high surface area-to-weight ratio that makes it an ideal insulator for residential and commercial buildings. Nowadays, fiberglass insulation does not irritate the skin like it used to and its manufacturing process is more environmentally friendly than it used to be. And, many manufacturers are using recycled glass.

Its benefits.

Fiberglass insulation is a cost-effective way to insulate your home. Not only could you see some savings on your heating and cooling bills, but it can also help reduce noise pollution. It is also non-combustible and non-absorbent.

Fiberglass insulation is also easy to install. You will not have to wait long for fiberglass insulation to be installed. While the installation process can be easy, it is still best to call in the professionals, like tthose at Lewis Insulation, to get it installed.

The type of fiberglass insulation we install is mold and mildew resistant. So you will not have to worry that your new fiberglass insulation is retaining moisture and possibly causing more harm than good to you and your family.

Its cost.

Fiberglass insulation is a budget-friendly option for many homeowners. You still get many of the same perks as other types of insulation, but fiberglass is one of the least expensive options on the market today.

Its efficiency.

Fiberglass insulation can help increase the energy efficiency of your home. It helps to slow the spread of heat and cold by trapping pockets of air. This helps keep your home cool in the summer and warm in the winter. Plus, it helps the amount of outside noise that comes into your home.

There are many different reasons fiberglass is such a popular choice in insulation material, contact us to find out more!

Learning the Why’s & What’s of Attic Insulation

So you may already know how important attic insulation is to the comfort and energy efficiency of your home. But do you know why? And what kind is best for your unique home? As experts in attic insulation for Rogers and the surrounding areas, we’d like to provide you with some benefits to insulation in general as well as a few facts about the different insulation types we offer. We hope this post can help point you in the right direction.

The Why’s

  1. About 25% of heat is lost through your attic. Heat escapes out of the roof of the attic thanks to poor insulation.
  2. Proper attic insulation could help you save money on heating and cooling bills and increase the comfort level of your entire family.
  3. By having your attic insulation replaced, you can essentially ensure you are not letting money escape through the ceiling.
  4. Proper attic insulation can also allow for even temperature distribution within the home as well as provide moisture control, and contribute to a more environmentally-friendly footprint for your home.
  5. By having your current insulation removed and new insulation installed as soon as possible, you can ensure the sound structure of your home.

The What’sattic insulation

  1. Closed cell spray foam insulation can expand to reach hard-to-fill voids, which is great for spaces like attics, which often have smaller and more out-of-the-way spots that need to be insulated. You should see some long-term savings on your heating and cooling bills with closed cell spray foam attic insulation.
  2. The two other types of attic insulation we install are fiberglass and cellulose attic insulation. These types of blown-in insulation have almost the same R-value, and they are both environmentally friendly. Cellulose is made out of recycled newspaper and fiberglass is made out of sand, both of which are renewable resources. Fiberglass and cellulose attic insulation are also very energy efficient, so you should see some savings on your heating and cooling bills in the long run with these types of insulation as well.

Not sure which type of attic insulation is best for your home? Give us a call. We can advise you on which type will best suit your needs and keep your home warm in the winter and cool in the summer.

How it Works: Heat Flow & Foam Insulation

Everyone knows that foam insulation and insulation in general helps keep the home temperate. But, how exactly? At Lewis Insulation, we are experts in all types of insulation, specializing in foam insulation for Eden Prairie and the surrounding areas. We get many questions about how insulation works and we’d like to share a brief rundown of the concepts of general heat flow as well as what makes foam insulation so good at what it does.

Conduction, Convection & Radiation

Conduction is the way in which heat moves through materials. Insulation’s job is to slow down this conductive heat flow and keep the heat from moving from outdoors to indoors.

Convection is the ways heat circulates through liquids and gasses. Hot air rises and cool air sinks. Home insulation slows convective heat flow.

Radiation is heat that travels in a straight line, heating anything solid that lies in its pathway. Home insulation reduces this acquisition of heat and is most effective when directed towards airflow.


Home insulation and foam insulation is integral in decreasing the flow of heat by offering resistance to the movement of it. In the cooler months, without insulation, hot air moves from heated areas to cooler areas of the home. The cold temperatures outside create the need for your home’s heating system to compensate for the loss of heat; constantly trying to fill in where heat has escaped. During the hotter months, cold air that is lost when heat enters and invades a space is then made up for by your home’s cooling system. It is your insulation’s job to stop this flow of heat and allow your systems to efficiently keep your home warm or cool. So, when open gaps in a building are filled with insulation, they reduce convective heat loss.

All types of home insulation come with an “R-Value”, a rating applied to an insulation type’s ability to resist conductive heat flow. Closed cell spray foam insulation has one of the highest R-values on the market today.
Closed cell spray foam insulation works well in difficult to reach nooks and crannies, like attics and crawl spaces since it is sprayed onto these surfaces.

These are only a few reasons you should consider closed foam insulation for your home. Call us and we can tell you even more!
